DISINFECTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 495,563, dated April18, 1893.. Application filed .Tune 13, 1892. Serial No. 436,540. (Nomodel.)

To a/Zzcwm it may concern:

Be it known that I, SANFORD G. PLUMB, a citizen of the United States,and aresident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Disinfecting Apparatus, of whichthe following is a specification.

My invention relates to disinfecting apparatus and has for its object toprovide a simple, cheap and eifective device whereby a certain amount ofdisinfecting matter may be automatically supplied to a closet tank orcistern or other similar device, the apparatus being capable of beingplaced in the usual tank or cistern and being removed therefrom and tobe used without any change or alteration in the arrangement of theordinarily constructed tank; and to these ends my invention consists inthe disinfecting apparatus, constructed, arranged and operatin gsubstantially as hereinafter set forth.

Referring to the accompanying drawings, I have illustrated a tank in theconventional form, a part being broken away to show the construction ofmy disinfecting apparatus.

The tank A, may be of any desired and proper form and be provided withthe usual valves for the exit of the water and the pipes for supplyingit, none of which are shown as they form no part of my invention andtheir construction and operation are understood by those skilled in theart.

My disinfecting apparatus consists of what I have termed a Siphon, jar,bottle or vessel B, and this may be of any size or shape and of anymaterial desired, it being preferably contracted toward the top asshown.

Connected to or formed in the sides of the jar or bottle are the nozzlesC, D, the latter of which is arranged near the bottom of the vessel,while the former is arranged preferably about half way up or near themiddle thereof, although of course the precise height or arrangementwill depend upon various considerations as to the relative diameter ofthe Vessel compared with its height and the amount of disinfectingmaterial to be used. These nozzles are each provided withavalve whichmay be of any desired structure or form, preferably an ordinary checkvalve. The valve c, attached to the nozzle C, is arranged to be normallyclosed from the outside and to be opened by pressure from the inside,while the valve d, is arranged to be normally closed from the inside andto be opened by pressure from the outside of the Vessel.

Inside the vessel between the nozzles is placed a suitable disinfectantE, which may be of any suitable material as permanganate 6c of potash,chloride of lime or any other Well known disinfectant, although Ipreferably use my odorless disinfectant, but this of course forms nopart of my present invention and any material which is suitable for thepurpose can be employed.

The vessel B, having been charged with the disinfectant can be placeddirectly in the tank in any suitable position and is ready foroperation. 7o

In using the device, supposing the tank to be empty and Water to beadmitted therein, as it rises in the tank above the nozzle D, thepressure of the water on the valve d, opens the valve and allows thewater to pass into the vessel B and percolate through the disinfectanttherein, and as the tank becomes filled the pressure of the water in thetank on the valve c, of the nozzle C, will prevent it being opened, sothat eventually the water will rise 8o in the vessel after passingthrough the disinfectant to substantially the level of the water in thetank and it will so remain until the water is delivered for iushingpurposes. As the water flows from the tank and the level falls below thelevel in the vessel B, the pressure of the impregnated water in thevessel Vwill force open the valve c, in the nozzle C, and allow theimpregnated Water to flow into the tank and thence through the pipes and9o connections therewith, which will be thoroughly disinfected thereby.It will be observed that under these conditions the valve d, in thenozzle D, is closed so that the disinfectant E, cannot flow out throughsaid nozzle and it remains in the vessel, ready to receive anothercharge of Water to be impregnated when the tank is again flushed. Theseoperations will be gone through with until the disinfectant in thevessel loses its disroo infecting properties when the vessel can beremoved and recharged and it will be seen that this can readily be doneand a neW vessel properly charged substituted for the exhausted onewhich can be removed to a convenient place for charging, or it can beremoved from the tank and charged and immediately replaced, and it willalso be seen that no change or modification in the tank is neeessary.

While I have thus described and illustrated the preferred embodiment ofmy invention and its mode of operation, it will be understood that thedetails of Construction and operation may be varied without departingfrom the spirit thereof and I do not therefore limit myself to theprecise Construction or arrangement shown.

lVhat I claim is- The combination With a tank, of adisinfeotingvesselmonnted in the tank, and having two openings in itsside at diferentdistanees from its base and below the normal level ofthe Water in the tank, one of the openings being provided with a Valveopening inside the ves- Sel, and the other With a valve opening outside,and arranged to contain disinfeeting material between the valves wherebythe Water enters one valve, pereolates through the material and is heldin the receptacle and When the tank is flushed, it will flow out of thereceptacle into the tank, substantially as described.

In testimony whereof I have signed my name to this speoieation in thepresence of two subscribing Witnesses.
